Title: Railless ground conveyor installations and conveyor cars therefor
IPC: B62D1/24
Filed: 1974-06-26
Abstract: 1479481 Automatic control of vehicles BURO PATENT AG 26 June 1974 [26 June 1973] 28427/74 Headings G3N and G3R An automatic load conveying arrangement includes a passive guide track having switch points and a number of cars each adapted to follow a route by scanning the guide track and responding to a track marking which causes a target distance to be compared with the distance covered by the car until a predetermined relationship is attained when the steering mechanism operates as appropriate to direct the car to its predetermined destination. In the system described each car is provided with a multiple scanning head comprising scanners 36 1  for sensing the guide track, scanners 362 for providing steering corrections to restore scanner 36 1  over the track and scanners 363 for detecting branches and ordering gross steering changes in order to change tracks. The steering mechanism includes cams 28 rotated with the wheel assembly 56 and used to select the scanner output for the control of steering motor 48. The track consists of coloured strips, bands of ferromagnetic material or metal strips which can be detected by the scanning heads and the code marks may be provided by interruption of the track as shown at D1 in Fig. 1. In operation the scanner 22 initially receives an auxiliary signal E which enables the control system to commence measuring the distance travelled and disable the outer sensors 36 3 . This distance is measured by a counter and the count compared with the distance count stored in a programming device. The distance moved is measured and compared with the stored distance count until equality is obtained when scanners 36 3  are again enabled. If the scanners 363 sense the track A 1 the car will turn off on to the branch but if the car has passed the switch the car continues on the straight path. The instruction length D2 is used to provide a 'call lift' signal or other command instruction which may be remotely provided. The codes stored in the programming device can be changed by instructions from a remote ultrasonic transmitter or alternatively they may be manually programmed. In modifications of the track configuration a point marker may be used to enable the arrangement and to provide the code marking or alternatively, the code marking may be read by the auxiliary reading head.

Controlling by record-strip; assembling matrices.-In a check and control device for matrix release in automatically operated matrixsetting and line-casting machines, using signals for the release and responsive to the release of the matrices, the signals are converted into pulses and are stored separately and their numbers are compared with one another at the end of the line, delivery of the line being prevented if the values compared differ from one another. If the release signals are applied mechanically to the escapement mechanism, each signal also closes an electrical contact to produce a pulse, which is passed to an electronic or electromagnetic binary counter. If the signals are applied electrically, each signal is passed also to the counter. When a matrix is released, it passes across a light ray from a light source to a photo-electric cell to produce a pulse which is passed to a second counter. The light ray may be directed through apertures in the assembler channel plates, or across the collector before the star-wheel. The output of the counters is compared and if unequal produces a pulse which conditions a circuit to the assembler elevator magnet, which circuit is completed when the end-of-line signal is read.
